Just offering modern comparisons Tom. Frankly, I'd have rather had a Winchester 30-30 in that Charlie Fox Trot than an M-2.

I understand now, I thought my reference to the NRA magazine had confused you.
Now for the fun part, arguing about guns

I really doubt that the lever action would have performed much better, better caliber, but much lower capacity, and back in those days no one really thought about -40 degree temps when they designed a gun except maybe the Soviets.
It seems to me that the only advantage the lever gun would have would be extra leverage when you were trying to force the frozen action, and that is just as likely to cause breakage or other damage, the article notes that troops even had to pee on the BAR to thaw it out enough to function.
My Dad also has told me that the following winter it was necessary to fire the machine guns every so often (model `1917 water cooled .30's ) so the water in the barrel jacket would not freeze and split it, that was
with anti freeze mixed in.
